Title: Time axis error correction device
Inventor: YAMADA HIROSHI
IPC: G11B20/02
Filed: 1990-06-11
Abstract: PURPOSE:To suppress a velocity error and to improve the time axis correction characteristic by controlling a delay of a variable delay line based on a delay quantity control signal corresponding to time axis fluctuation of an input video signal per one horizontal scanning line. CONSTITUTION:A voltage controlled triangle wave generator 25 generates a triangle wave of negative polarity and it is fed to a variable delay line 19 as a delay quantity control signal. The input video signal by the variable delay line is not delayed by the delay quantity control signal for a start of one horizontal scanning period and a phase at the left side of a monitor screen is not fluctuated. Then the delay quantity is gradually changed over one horizontal scanning period and the delay in response to the time axis fluctuation is given. Thus, since the fluctuation of the time axis appearing at the right end on the monitor screen for each horizontal scanning period is suppressed before being inputted to an A/D converter 1, a velocity error unable to be eliminated only by a time axis error correction device using an APC circuit is corrected.

Title: Fail safe semiconductor device
Inventor: ASADA NORIHIRO
IPC: H01H37/76
Filed: 1991-06-25
Abstract: PURPOSE:To make a fail-safe semiconductor device small and inexpensive. CONSTITUTION:A wax-type thermostat is injected into a container provided around a transistor 2 on a silicon substrate 1, and the container is sealed by an insulator 5 made of organic material, such as polyimide. An interconnecting pattern 6 for current input/output wiring to terminals C, E, and B of the transistor 2 is positioned on the organic insulator 5. In case the transistor 2 has broken down by a short circuit, the temperature of the wax-type thermostat rises by heat from the transistor 2. Then, the wax-type thermostat undergoes phase change and becomes larger in volume. The expanded volume cuts off the wiring pattern 6 so that the output of the transistor 2 is shut off.

Abstract: PURPOSE:To suppress the roughness (fuzz) of the peripheral edge of metal wirings by interposing an insulating film of 2-layer structure which has a large etching rate layer at the lower portion and a small etching rate layer at the upper portion between the main surface of a semiconductor substrate and a wiring pattern forming photoresist.

The etching rates of the first and second layer films 7, 8 are R1, R2, and set to the relation of R1>R2. When a hole 9 is formed at the films 7, 8 of the 2-layer structure with an etchant, a sectional shape is formed in an inverted mesa shape, and since the height from the main surface of a semi-insulating GaAs substrate 1 to the upper surface of a photoresist 2 is raised by the 2-layer insulating film, it can suppress the fuzz by the deposition of the wiring metal film 10. Thus, an SiO2 coating layer 12 is formed on the films 7, 8, flattened, and when the second metal wiring layer 6 is further formed, the wirings 11, 6 are not shortcircuited to be preferably electrically separated.

The guttering surface of the sedimentation tank means the surface of a gutter taking out supernatant water from the sedimentation tank and the surface of guttering guiding supernatant water to a discharge port. When the vinyl chloride resin plates are bonded, they may be bonded to the entire guttering surface of the sedimentation tank or may be partially bonded to a surface receiving solar rays. By this constitution, the adhesion and growth of algae on the guttering surface of the sedimentation tank discharging supernatant can be prevented over a long period of time and, when algae are bonded during long-term use, algaes can be lightly rubbed by a soft brush.

Title: Magneto-optical recording medium
Inventor: ISHIDA MASAYA
IPC: H01F10/12
Filed: 1988-06-22
Abstract: PURPOSE:To obtain a magneto-optical recording medium which is capable of the high-density recording and a high transfer rate by using an amorphous alloy thin film of a specific composition containing an axis of easy magnetization in the direction perpendicular to the film surface. CONSTITUTION:A recording layer uses an amorphous thin film having an axis of easy magnetization in the direction perpendicular to the film surface. The composition of said thin film is expressed as CexGdy (Fe, Co, Ni)100-x-y in terms of an alloy. In this case, 0<x<=15 and 17<=y<=28 must be satisfied. The Curie point of the recording layer is dropped with addition of Ce and no remarkable difference is produced in the CN ratio with <=15% Ce content. Thus the optimum recording power can be reduced with no deterioration of the CN ratio. Then it is possible to obtain a magnet-optical recording medium which ensures a high transfer rate as well as the high density.
